Qualcomm aptX Lossless Bluetooth Codec announced, promises’ wireless’ CD quality ‘audio

Qualcomm aptX Lossless Bluetooth codec has been announced and is expected to be launched to supported devices later this year. The new Bluetooth codec is Qualcomm’s answer to Sony’s LDAC, and promises “CD quality” audio over wireless transmission with a maximum bit rate of around 1 Mbit / second. The new codec is expected to roll out to supported devices by the end of 2021 and will be supported on both source devices and headsets. It is claimed to be the most advanced Bluetooth codec from Qualcomm yet.

The new Bluetooth codec from Qualcomm is stated to support streaming at up to 1 Mbit / second, only slightly higher than the maximum bit rate of 990 kbit / second supported by Sony̵

7;s LDAC Bluetooth codec. The company says that the bit rate is variable, down to 140 kbit / second in congested environments with a lot of radio interference, to maintain the stability of the sound stream.

Qualcomm further claims that the codec can deliver CD-quality audio with 16-bit / 44.1 kHz resolution, with bit-by-bit transmission. That said, achieving this level of sound quality over Bluetooth will require a very stable connection with little radio interference around, so the possibilities will probably only be really achievable under ideal conditions. Under most real-world conditions, aptX Lossless will still offer better audio quality over Bluetooth than existing aptX codecs, and will likely match LDAC’s capabilities, but with the benefit of wider product support.

Currently, Qualcomm has a number of aptX Bluetooth codecs that are supported on various devices, including most Android smartphones and many computers and laptops as well. The latest codec, aptX Lossless, promises to build on existing technologies such as aptX Adaptive, and will theoretically be able to work with lossless audio streaming from services such as Apple Music and Tidal.

Although high-definition sound is best heard on wired headphones or earphones, improvements in Bluetooth features and stability make it possible to enhance the listening experience even over wireless transmission. Qualcomm aptX Lossless is expected to reach supported devices by the end of 2021, and will hope to bridge the sound quality a bit, while continuing to offer the benefits and conveniences of wireless audio.
